Can't we dream bigger though? For instance, I feel like templeOS's command line is unironically
conceptually superior than the linux commandline or any other unix. I should be able to mix text with 3d models or images or sound, pipe them between programs, etc. I should be able to pause a running program, save it to disk, and resume it later. There are all sorts of things that I should be able to do but can't, because of the deliberate unix fetishization of 1970s era computing.
>Command line interfaces are superior even today because the step from interaction to automation is as minimal as possible.
Agreed completely. In fact, the OS should force GUI programs to all speak a coherent language so that you can automate them and pipe data between them. And if the machine is going to serve the user, the user should be in control of the GUI, they should be able to move buttons and UI elements around into the configuration they prefer. This would only be possible if GUI programs had minimal control over actual UI layout, which would make webdevs angry. But given the state of web UI, I think that's an acceptable sacrifice.
Much of the above was possible in lisp machines. But sadly I don't think it would be possible to create such an OS today (unless the "OS" is running in a linux VM and using linux for the actual hardware interface) due to the sheer diversity of hardware. And the closed source nvidia driver would ensure that you never got cool graphics.
